i'It is.falsofanhbjectlosthis. invention tcpfi'lide an air conduitcomposed of sections of coiled wire, the end of each section beingconstructed to cooperate With the end of another section to form aconduit of various lengths.

It is also an object of this invention to provide a conduit section,composed of a coil of wire, surrounded by a jacket of burlap or canvas,so that the air may pass from the conduit out through the side of theconduit, but smaller grain cannot pass into the conduit.

These, and other advantages will appear from the following descriptiontaken in connection with the drawings in which:

Figure 1 shows an air conduit composed of two or more sections, one endof each being larger than the other part of the section, and the smallerend of one section threaded into the large end of another section.

Figure 2 shows an air conduit similar vto that shown in Figure 1, exceptthat the sections are not connected.

Figure 3 shows an air conduit composed of two sections of coiled wire,one end of each section having therein a band around which the other endof the other section is threaded.

Figure 4 shows a conduit similar to that shown in Figure 3, except thatthe sections are not connected.

Figure 5 shows elements of an air conduit composed of a pair of sectionsof coiled wire, the sections being of like diameter throughout. Thesesections are united by a short section of coiled wire the short sectionbeing of greater diameter than the main sections.

In the various iigures, there is shown a plurality of sections of coilsof wire formed to cooperate in producing a Ventilating and dryingconduit. These sections of coiled Wire may be united to form a conduitof any desired length and the coil may be varied in size to form aconduit of various dimensions.

In Figure 1, there is shown a coil, which is of 55 @enligne fer-geilsfe@ad Qfialoiheracoilf; `rllhesercoile arefthre de en toanotherf. Thesecoils Ywhen;.-used-V in any number form at.cond-uit` or, uniformidiameter other coil is Figure 1, illustrates these two coils, unitedwhile, Figure 2, shows the coil separated and as they appear before theyare united to form a conduit. In Figures 3 and 4 there is shown a formof conduit in which the ends of the coils are prevented of lateralmovement in regards to each other by means of bands 6 and 8. The number5, is used to designate a coil that is uniform in size, throughout itslength. In one end of this coil 5, is the band 6, which serves as partof a coupling element for the uniting of two coils, such as coil 5, anda coil l. The coil 1 has in one end thereof the band 8, serving the samepurpose as the band 6. The end of coil 5, free from the band, isthreaded on the end of coil 1, Which has the band 8. The end of the coilthreaded onto the band is slightly larger thanthe rest of the coil sothat it may easily turn on the band. The bands 6 and 8 prevent the endsof the coils slipping laterally with each other and the slightlyenlarged ends of the coils provide space for the bands withoutdecreasing the inside diameter of the conduit.

Figure 3 shows the coils 5 and 1, united in the manner to form aconduit. Any number of these coils may be united as shown in Figure 3,to form conduits of any desired length.

In Figure 4, these two coils are shown apart, and in the position to bethreaded one on to the other. It will be observed that in the form shownin Figures 1, 2, 3 and 4, the sections are united directly one toanother by threading one onto the other.

In the form shown in Figure 5, the sections are united by means ofseparate elements.

In Figure 5, the coils shown are indicated by the numerals 9 and l0.These coils are uniform in size throughout, so that when they are unitedend to end they form a continuous uniform passageway for air and heat topass through.

The coils 9 and I0, are connected by means of a closely coiled, largercoil Il, to form a con-.- Y

sectie tinuous conduit. Each end of the coils 9 and I0, 4

is threaded into one end of the larger coil I l.

There may be in a single conduit formed of a large number of the coils 9and l0, united by the larger coils Il.

The coils 9 and I0, may be of any desired length and of any desiredsize, and are united by means of coils l I, which have about four, turnsof closely coiled wire in their construction. Each one of the variouscoils has its end coils, about two, closer together than the coilsbetween the ends. The end coils must be closer together, so that theycan serve as threads in uniting the various coils or elements. The coilsbetween the end coils may be spaced apart any desired disparticles fromgetting in the conduit, the conduit as a whole may be surrounded by a'wrapper. or cover of burlap, canvas, or very Vclosely meshed wire, asindicated by the numeral I2.

What I claim as my invention is:

1. In a conduit for air, a plurality of elements forming said conduit.each element being formed of a coil of Wire, a sleeve in one end of eachcoil and the other end of each coil being threaded onto the sleeve endof another coil.

2. A conduit for lair, composed of a plurality of sections, each sectionbeing iiexible and unite'd to another section by means of a sleeve sothat it can rotate with relation thereto but cannot be movedlongitudinally or laterally thereof, each with relation to each other.

Aa conduit of uniform innerl diameter.

4. In a conduitlfor air, a'fpluralityof elements vrforming said conduit,each element being formed of a coil of wire, one end of each coil beingthreaded into one end of another coil, so that each coil cannot movelongitudinally with respect to the other coil and frictional means toprevent the threaded parts of the coils moving laterally CLARENCE L.WISE.
